A bicycle disc brake caliper includes a lever arm rotatable about a pivot axis and a rotary to linear linkage between the lever arm and a brake pad translating rotation of the lever arm in an advancement and a return direction to linear advancement or return, respectively, of the brake pad. A return spring is coiled about a spring axis as a first end is fixed against rotation relative to the lever arm and a second end is rotatable with the lever arm about the spring axis. A screw is selectively rotatable about a screw axis and is operatively associated with an end of the spring to selectively rotate the end of the spring relative to the other end of the spring about the spring axis by rotation of the screw independent of movement of the lever arm to adjust the return force applied by the spring to the lever arm.
